Why do Christians think Christ is God?

[Some basics for the saints who wish to build their argument]
The esoteric (revealed only to a particular group – John 10:26) enigma (the unexplainable) of Jesus
1. The embryonic Old Testament witness
How the idea of the deity of the Christ begins to form in the Old Testament
A. From a case for complexity in our singular God
If God is one, then how can Jesus be God?
Deuteronomy 6:4 “One” is from the Hebrew echad. It is apparently a complex unity, or a one that can be plural. Compare ‘one’ in Genesis 2:24 and perhaps Numbers 13:23 in illustration.
Matthew 28:19 – “…the name (singular) of the father, son and holy spirit”
B. From comparison of Old and New Testament references
I. e. Isaiah 45:22-24 with Philippians 2:11; Psalm 102:25-27 with Hebrews 1:10-12
2. His embodiment of the Word
John 1:1, 14
Colossians 2:9
3. His express words
Compare John 8:58 w/ Exodus 3:14
4. The empirical witness of His works
John 10:31-33
5. His entertainment of worship
Compare John 20:19-31 w/ Revelation 22:8, 9
6. The extended references in the apostles’ writing
God’s effulgence - Hebrews 1:2
His encompassment of everything beginning and end - Revelation 1:17
Conclusions:
We have already seen that the Apostle Paul was open as he equated Jesus with the God of Israel in Isaiah’s prophecy of future obeisance to Yahweh/Jehovah. If Jesus is this same Lord, then He is somehow Yahweh of Israel. But it also stands that if He is Yahweh of Israel, He is Lord of all and therefore Lord of us.
He is Lord.
Will you bow before Him while you yet live? It is a declared certainty we all will bow to Him one day in our future.
Better now than later.
